摘　　要：采用特定组成的溶剂油,在一定温度及搅拌条件下对国内某废塑料加工厂生产的废塑料再生颗粒进行液化处理,测定废塑料再生颗粒在特定溶剂油中的液化速率及废塑料液化液的黏度,建立了废塑料液化液黏度与废塑料再生颗粒含量的关联式。试验结果表明,废塑料液化液中废塑料再生颗粒的含量是影响再生颗粒液化速率和废塑料液化液黏度的主要因素。By using a specific composition of solvent oil and subjecting the recycled waste plastic particles produced by a domestic waste plastic processing plant to liquefaction treatment under the conditions of a certain temperature and stirring rate,the liquefaction rate of recycled waste plastic particles in the specific solvent oil and the viscosity of waste plastic liquefied liquid were measured,and the correlation formula between the viscosity of waste plastic liquefied liquid and the concentration of recycled waste plastic particles was established.The experimental results demonstrated that the mass fraction of recycled waste plastic particles in the waste plastic liquefied liquid is the main factor affecting the liquefaction rate of recycled waste plastic particles and the viscosity of waste plastic liquefied liquid.
